SHINGLE-LOCK-APPLYING MACHINE.

Application filed September 18, 1922. Serial No. 589,035.

Shingle-Lock-Applying Machines, of which the following is a specification.

Among the principal objects which the present invention has in view are: to apply locks or fastening devices to shingles of certain classes with rapidity and ease; to secure the said looks upon flexible roofing shingles quickly and with ease; and to pro vide a machine for accomplishing the above stated purposes which is simply and cheaply constructed.

Description.

The shingle lock for attaching which to certain classes of shingles the present machine is designed is shown best in Figures 1 and 3 of the drawings. It is preferably constructed from sheet metal and has a body portion 10 of desired height, generally equal to the thickness of a sheathing board or roofing strip used for supporting roofing shingles. From opposite edges of the body 10 are extended the wedges 11 and clips 12. The said wedges and clips are extremities of overturned flanges of the body 10. One of the clips 12 is formed at the end of an elongated extension 13. The opposite clip 12 is at the extremity of a shorter extension 14.

.are pressed through and clinched upon the shingles indicated by the numeral 15.

The shingles 15 for which the locks above described are particularly designed are constructed of semi-flexible material such as heavy roofing board or asbestos slabs. Shingles thus constructed are benefited by reinforcement disposed lengthwise. thereof. Thls is provided in the present instance bv means of the extensions 13 and 14 which st ffen or strengthen the shingles while the CllPS 12 being clinched thereover hold the structure rigid.

Certain of the locks 10 are shorter than others, and for this reason the heads 16 with which the press frame 17 is provided have two sets of supportin recesses indicated by the numerals 18 an 19 respectively. When loading the heads 16 with locks to be attached to shingles the wedges 11 thereof are disposed in the recesses 18 and 19, the frame 17 being held in the upraised position shown in Figure 1 of the drawings, the unclmched clips 12 resting in juxtaposed relation to the stripper heads 20. The stripper heads 20, as best seen in Figure 4 of the drawings, are disposed at the end of plungers 21 held in the heads 16 and in bored recesses 22 provided therefor. Around each of the plunge-rs 21 extends the spiral spring 23 with which each stripper is provided. The spring 23 normally advances the head 20 to the position shown in Figure 1 of the drawings, while the spring 23 compresses as shown in Figure 3 of the drawings to permit the head 16 to approach the shingle 15 sufficiently to overturn the ends of the clips 12 on the anvil 24.

The frame 17 consists of a series of reach bars spaced apart a distance equal to the width of the shingles to be provided with locks. There may be two or more of said reach bars in each frame. A hand bar 25 unites the various reach bars as also does the brace 26 which is extended across and secured to said reach bar near the hinged end thereof. As shown best in Figure 1 of the drawings the reach bars of the frame 17 have a series of hinge brackets 27 by which the frame is pivotall mounted on a hinge rod 28 supported above the base board 29 by brackets 30.

The machine is peculiarly adapted for placing the locks on what may be termed imitation shingles, or shingle strips of various lengths such as shown in Figure 5 of the drawings, the exposed edges whereof are slitted to form spaces 31 imitating the part ings between shingles of conventional form. When applying locks to shingles of this character the several locks 16 are loaded before the frame is depressed. In this condition the frame forces the various clips 12 upon the anvil 24 so that the curved end of the said anvil curls the said clips to the osition shown in Figure 3 of the drawings. en pressure is removed from the hand bar 25 the springs 23 extend the stripper heads to prevent the lift of the shingles 15. Prior to releasing the frame 17 it is moved slightly sidewise, the pressure being sufiiciently relieved to avoid pulling the locks sidewise. llhis frees the various looks from the heads 16, the wedges 11 sliding easily from engagement with the recesses 18 p and 19.

The anvils 24: are preferably made of metal of any suitable character, a groove 32 being routed therein. The ends of the said groove 32 are curved as best seen in Figure 3 of the drawings for curling the clips 12 when forced thereinto.

A gage strip 33 is held in position by wing nuts 34 so that the shingles 15 or shingle strips 15 may be quickly adjusted on the base board 29.

It is obvious that this machine employed in the manner as above described enables the mechanic to quickly apply and with ease a large number of the locks to single piece shingles or strips of shingles laid on the base board 29 against the gage 33. It is also obvious that with shingles thus provided the construction is reinforced and the labor of laying or mounting the shingles on the roof is facilitated and quickened. I
